Referring to Fig. 1 of the drawings, 2 designates one of=thelegs orstandards support- 1ng a winding machlneofrthe usual gang or multiple-unit type, and 3indicates the bed or frame on which the-winding units are mounted. %The winding. mechanism ashereinillustratedt is of: a well known type comp'rising a (llLlIH OII drive-roll 5 and a rotatable cop-hold- 'ersor yarn-receiver 6 on which the package'is wound. The cop-holder 6-is carried at the end of a swinging arm, indi'catedvgenerally upright9,

of a reciprocating thread-guide 10. The

to expedite thread-guidewldis mounted to slideon-h-ori- .7 zontal tracks or 'ways 111 and 12 and carries a roller or bowl 13 engaging a helical groove 14 in the rotating cam 15 from which it is reciprocated. The construction of the winding mechanism as above indicated is well known to those versed in the present art and is therefore not herein illustrated in detail.

Each winding unit is usually provided with a tension-device for applying resistance or tension to the draft on the yarn as it feeds to the cop or package being wound, and the present drawings illustrate a disk-tension for this purpose. In Fig. 1 the tension-device is shown as mounted on a bracket 17 bolted to the front of the frame of the winding machine at 18 and having a horizontal shelf or rest 19 supporting a vertical spindle 20. A pair of opposite tension-disks 21 are mounted on the spindle 20 with a weight-holder 22 slidable on the spindle thereabove and carrying a suitable number of weights 23 which apply pressure to hold the tension-disks against the strand of yarn drawing therebetween. The weight-holder 22 is preferably arranged to bear against a spring 24 coiled around the spindle 20, whereby a yielding pressure is exerted on the upper tension-disk to press it down against the lower disk. The strand of yarn y is guided in an opening or guide-eye 26 at one side of the shelf 19 and draws across the top of the shelf to lead between the two tension-disks 21. From the tension-device the strand 1 draws through a suitable slub-catcher 27, as usually provided, and thence leads to the thread-guide 1O tobe fed therefrom and traversed thereby on the cop or package being wound.

In delivering yarn or other strand material from cops, bobbins and other types of headless packages the strand is usually drawn off over the end of the package, the supplies being arranged below the winding-units with their axes in line with the point to which the yarn delivers as it feeds through the tensiondevice. In the present application of the invention a horizontal rod 28 is provided as a support for a plurality of supply-holders, the rod extending the length of the winding 1nachine with its ends held in brackets 29 attached to the legs 2. As indicated in Figs. 1 and 2, the brackets 29 are fastened to the web of the legs 2 by means of clamps 30 secured in place by bolts 31, and the rod 28 is held in hubs 32 at the ends of the brackets by means of set-screws 33, see Fig. 4.

It will be understood that a supply-holder is provided for each winding unit and the construction and arrangement of the present improved device is as next described. The main element of the holder consists of a rotatable member constructed in the form of a hub or annulus 35 and provided with a plurality of circumferentially disposed bosses 36 drilled to I receive the radial spindles 37. Preferably, the bosses 36 are tapered toward their outer ends to adapt them to enter the enlarged end of the bores in the bobbin-tubes b to center the bobbins on the spindles. The circular hub or annulus 35 is rotatable on a bearingmember 40, see Fig. 3, secured fast A cap or disk 46 is fitted against the edge of the rim 45 to retain the hub 35 in place on its bearing, the disk being fastened to the side of the member 40 by means of screws 47 screwed into lugs orbosses 48 projecting from the side of the flange 43. Through the above described construction the hub or annulus 35 is mounted to rotate on the member 40 to bring the spindles 37 successively into vertical position with their axes alined with the guide-eye 26 to which the strand delivers as it feeds to the tension-device.

Means are provided for retaining the rotatable member or annulus 35 in fixed position after each rotative movement thereof. As herein shown this means consists of a detent-latch or pawl 50 which engages with suitable depressions or slots 51 in the side of the hub 35. As a preferred form of construction the pawl 50, shown in enlarged perspective view in Fig. 5, is constructed from a strip of spring metal bent into shape to adapt it to be hooked through an opening 53 in the side of the plate or disk 46. The opening 53 is in the form of an elongated slot which is interrupted by a cross-piece 54 formed by slitting the metal at the sides of the slot and bending it outwardly in the shape of a loop as shown most clearly in Fig. 4. The detent latch 50 has a flat end 55 adapted to overlie the side of the disk 46, and beyond this portion it is bent into a square-sided loop 56 which passes under piece 54. Beyond the loop 56 the latch is inclined inwardly in a length 57 having its end bent around in a toe-piece 58 adapted to engage with the V-shaped grooves or slots 51 which provide ratchet-teeth or stops on the side of the rotatable hub 35. Through the engagement of the toe 58 of the pawl 50 with the grooves 51 the hub 35 is restrained from unwarranted or accidental turning movement, but when it is required to rotate the hub to bring a fresh bobbin into delivering position the pawl yields readily and rides along the face of the hub until it engages the next succeeding groove.

The method of operation of the complete device is as next explained: Assuming that a bobbin B is in place on the uppermost spindle 37 with its alin-ed with the guide-eye 26 through which the strand ;2 feeds, as the winding machine is operated the material is and around the crossdrawn off from the bobbin and Wound onto the cop-holder 6 to build the desired form of r :its method of application.

As the winding proceeds and the supply of package.

yarn on the delivering bobbin becomes'de pleted the operator places a fresh bobbin on the next forward spindle 37, just before the 4 end runs out on the first bobbin. As the last.

few coils of yarn are pulling off from the delivering bobbin the operator shifts the fresh bobbin B into delivering position by turning the supply-holder hub on its bearing 45. As the hub 35 is rotated the pawl rides out from the notch or groove 51 with which it is engaged and springs into the next notch just as the new bobbin is brought into vertical position. The complete operation of placing the fresh bobbin on its spindle and adjusting it to delivering position may be effected by a'single manual movement, the operator impaling the bobbin on the spindle and pushing it upwardly With a circular mo tion of the hand. Meanwhile, the operation of the Winding machine is arrested by the action of its automatic stopping-device as usually provided, and the operator has only to tie up the end of the fresh bobbin with the trailing end from the package, the spliced yarn being then drawn into the tension-device and slub-catcher by the automatic threading action of these devices.

The operation of placing a fresh bobbin on the holder and adjusting it to delivering position as the end runs out on the spent bobbin is repeated as becomes necessary during the Winding operation, and with the present improved device very little time is required for resupplying the machine with yarn.'

Each time a new bobbin is applied to the holder and turned into delivering position the empty bobbin-tube or yarn-carrier Z) is carried over to the right, as viewed in Fig. 2, and finally as it is turned into position with its spindle inclined downwardly, as

' represented by the dash lines in Fig. 1, the

empty tube 6 Will drop off from the holder to be cast into a suitable receptacle or bobbinbox which may rest'on the floor at the front of the machine. As a consequence of the automatic doffing of the spent bobbin and the simple method of applying a fresh one in its place, the interval during Which the Winding is arrested is very brief and therefore ,7 the loss of production is materially reduced as compared with the-usual method where an exhausted bobbin must be first removed and a fresh bobbin placed on the same spindle.

While the device is herein described and illustrated as embodied in a preferred form of construction, the structure and arrangement of its parts may be varied at will without departing from the spirit or scope of the invention Moreover, the improved device is susceptible of various uses in transfer processes otherthan that herein described, and the invention is therefore not limited as to What I claim' is: 1.
